Question

Help me 45*2+B=900 решить

Answer 1

$45*2+b=900\\ 90+b=900\\ b=900-90\\ b=810$

Answer 2

To solve for B, we first need to simplify the equation by solving for the expression on the left side of the equals sign:

45 * 2 + B = 900

90 + B = 900 (since 45 * 2 = 90)

Next, we want to isolate the variable B on one side of the equation. We can do this by subtracting 90 from both sides:

90 + B - 90 = 900 - 90

B = 810

Therefore, the solution to the equation 45 * 2 + B = 900 is B = 810.
